It reminds me of a recruiter I spoke to who asked me how much experience I had with "winforms". I said "None, I've never heard of that" and she couldn't believe it. She went into this tirade about how five years of experience with winforms was required for this job and how could I not know anything about it, and was I sure I didn't have at least some exposure somehow to winforms somewhere.

Very odd experience and the only time I've never had someone get angry in a context like that. I guess if you're a recruiter and recruiting for a job that lists winforms as a requirement you may think that's a super critical thing and not have any conception of the relative importance of knowing things like that.

I didn't go forward with the recruiter and I've never bothered to check what winforms are, but I assume it's some kind of library for creating GUIs in Windows and I further assume I could have been productive with it in a day or so.
